CULTIVATOR ATTACHMENT.

To all tlv/7mm it may concern.'

Be it known that we, GEORGE lV. FARMER and doi-IN lV. MILLER, citizens of the United States of America, residing at Sunset, in the county of Montague and State of Texas, have invented new and useful Improvements in Cultivator Attachments, of which the following is a specification.

rl`his invention relates to an improved implement which is in the nature of an attachment for cultivators and the like, said implement or attachment comprising a plurality of earth-engaging blades which may be mounted for operation upon the stock or standard of a plo,Y or cultivator beam for the purpose of crushing and pulverizing the surface of the soil.

l/Vhen heavy rains occur soon after the planting of seed, it frequently happens that the soil becomes caked and hardened, thus preventing' the seed from sprouting and necessitating replanting at a considerable expense of time.

A particular object of the present invention is to provide an implement whereby the soil may be successfully and effectively broken and pulverized, wherever seed has been planted in drills, thus loosening and reducing the surface and enabling the seed to sprout successfully where without such treatment the sprouting would be impossible.

lVith these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of part-s which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing-Figure l is a top plan view of the improved cultivator attachment showing the same applied to a plow foot, the latter being shown in section. Fig. 2 is a front elevation. Fig. 3 is a perspective detail view showing one of the earth-engaging blades detached.

Specification of Letters Patent.

Application led September 9, 1910.

atented Mar. "2, 1911..

serial No. 581,147.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved cultivator attachment includes two arms or wings l, 1, which are disposed in an approximately vertical plane, transversely of the implement or carrying member with which they are connected, as will be hereinafter described, and each of which is apertured for the passage of a fastening member, such as a bolt 2, whereby the. wings may be mounted securely in position upon a plow foot 3. The opposed faces of the wings are provided adjacent to the apertures with interengaging teeth el, whereby the said wings, when the fastening member is tightened, will be held very securely in adjusted position.

Each of the wings is provided adjacent to its lower edge with apertures for the passage of a plurality of pivotal members such as bolts 5 and adjacent to its upper edge with a plurality of arcuate slots 6 which are concentric with reference to the bolt-receiving apertures. Pivotally mounted upon the bolts 5 are blades B, each blade including an upstanding flat shank portion t3 and a rearwardly extending earth-engaging cutting member 7 having a convex or arcuate cutting edge 8 and terminating adjacent to its rear edge in a laterally extending suitably curved flange portion 9j The shank portion G of each blade is provided with non-circular apertures l0, 1l for the passage, respectively, of the pivot-al bolt member 5 and of a fastening bolt 12, which latter extends through one of the arcuate slots G in the wings or arms l. The earth-engaging portions 7 of the blades are made right and left handed with reference to the two wings, as will be clearly seen in Figs. l and 2 of the drawings. It is evident that by exchanging or transferring the blades from each wing to the opposite one, the blades may be arranged to move the dirt inwardly or outwardly with reference to the center of the device.

From the foregoing description, taken in connection with the drawing hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. The improved cultivator attachment is of an extremely simple construction, and it may be readily applied to any ordinary plow stock, thus enabling a single plow stock to be utilized for a Variety of purposes. As will be readily seen, the individual blades are capable of being easily7 adjusted to Various positions with reference to the carrying wings or arms, and the latter may likewise be adjusted at Various angles with reference to each other and to the plow foot with which they are connected. It will thus appear that the blades may be adjusted in such a manner that the surface of the soil will be broken and pulYeriZed without stirring. agitating or displacing the saine to any considerable extent, while. on the other hand, when it shall be desired to do so, the surface oit the soil may be not only pulver-ized but also displaced laterally in any direction.

Having thus described the invention7 what is claimed as new, is

l. A cultiyator attachment comprising two wings disposed in an approximately Vertical plane, means for connecting said wings pivotally and adjustably with each other, and a plurality of blades having fiat upstanding shank portions pivoted upon the wings7 intermediate twisted portions and rearward extending blades lying .in planes substantially at right angles to the upstanding shank portions; and means for securingthe shank portions of the blades at Various adjust-ments about the axes of their respective pivots.

2. A carrying element consisting of a plow toot, a pair ot wings disposed .in a substantially vertical plane, means for connecting said wings pivotally and adjustably together and upon the plow foot; blades having tlat upstanding shank portions, intermediate twisted portions and rearward eX- tending earth engaging portions, the latter being' disposed in planes substantially at right angles to the upstanding shank portions, bolts extending through the upstanding shank portions and through the wings to pivotally support the shank portions. and adjusting bolts; the wings being provided with arcuate slots concentric with the pivotal bolts for the passage ot the adjusting bolts.

in testimony whereof we atliX our signatures in presence of two witnesses.
